Technical details
Endpoint
GEThttps://api.aisa.one/apis/v1/polymarket/closed-positions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical, resolved prediction market position data for a specific Polymarket wallet — particularly to analyze realized PnL, review trade outcomes, or audit activity on specific markets or events. Prefer this over open-positions endpoints when the user is interested in completed trades rather than live exposure.
Side effects
- Invalid or malformed wallet address returns a validation error
- Using both market and eventId parameters simultaneously returns an error
- limit exceeding 50 or offset exceeding 100000 returns a parameter validation error
- Wallet address with no closed positions returns an empty array
- Unknown conditionId or eventId returns empty results or an error
